1. Thou shalt not worry about bugs.
** Bugs in your software are actually special features.
2. Thou shalt not fix abort conditions.
** Your user has a better chance of winning state lottery than getting the same abort again.
3. Thou shalt not handle errors.
** Error handing was meant for error prone people, neither you or your users are error prone.
4. Thou shalt not restrict users.
** Don’t do any editing, let the user input anything, anywhere, anytime. That is being very user friendly.
5. Thou shalt not optimize.
** Your users are very thankful to get the information, they don’t worry about speed and efficiency.
6. Thou shalt not provide help.
** If your users can not figure out themselves how to use your software than they are too dumb to deserve the benefits of your software anyway.
7. Thou shalt not document.
** Documentation only comes in handy for making future modifications. You made the software perfect the first time, it will never need modifications.
8. Thou shalt not hurry.
** Only the cute and the mighty should get the program by deadline.
9. Thou shalt not revise.
** Your interpretation of specs was right, you know the user’s requirements better than them.
10. Thou shalt not share.
** If other programmers need some of your code, they should have written it themselves.
